GTS 250 x16/x4 worth it?

[ghomfp]

I've had this evga gts 250 512mb DDR3 graphics card for about a year now. I was just browsing ebay and found the excact same one for $45+$18 shipping, and thought i should dual them with sli. but my motherboard only has a x16 slot and a x4 slot. Is it worth the $65 or is the difference between one card and two on x16/x4 to insignificant to even bother?

it is better to have at least x8/x8 in SLI or CF. what is your mobo model? i never saw SLI capable board with x16/x4 before

My mb is an msi g45 870. The book for that specific mb talks about crossfire but nothing about sli..

Oops meant 870-G45

you need SLI certified board for SLI setup. if you want to use CF only board for SLI you're going to make some hack to make it work with your mobo
